Origami Dodecahedron

Thanks to Max Planck for original instructions.

Take a square postit 4x4, sticky bit down and on top.
Fold the bottom half up creasing it in half forming a 2x4.
Now fold the top quarter down on the front,
flip the postit over (back becomes front) and fold the top quarter down on the front (sticky bit attaches itself).
You should have a 1x4 postit, if unfolded 3x4.

side front

Fold left bottom corner to top edge and fold right top
corner to bottom edge, creasing, as follows:

Step 2: Fold corner 1 into the middle, so that the corner just meets the middle. Do the same for the other corners, in order. You should now have a hexagon, with two short sides and two flaps (labled x and y):

Step 4: Now you need to fold the corners 1 and 2 to touch the centre line. The fold meets the edges at points 3 and 4. To get the folds in the right place, make sure you have one straight line through 3-1-4-2. You should now be left with a pentagon:
